Abstract

Urbanization significantly impacts climate by intensifying the urban heat island (UHI) effect, leading to increased heat-related risks from climate change. Changes in land use and land cover (LULC) during urbanization processes exacerbate heat stress in growing cities. The urban surface composition, structure, and emissions from various activities contribute to local climate changes that can be more pronounced than global climate predictions. With over half of the world's population residing in cities, which are often densely populated, the current urban population of 55% is projected to reach 68% by 2050. Cities typically have temperatures that are 2-3 °C warmer than their surroundings, with nighttime and wintertime variations being the biggest. Urban climate impacts like these make inhabitants more susceptible to upcoming environmental shifts, which makes cities ideal locations for climate adaptation and mitigation. The urban heat island effect, which occurs when cities are much warmer than surrounding rural regions, can amplify the effects of heat waves and increase urban energy demand for cooling. Keeping the aforesaid knowledge in mind, Kochi, a coastal city in Kerala State has been chosen as the study region for further detailed investigation. The study aims to evaluate the urban growth in the city over two decades from 2001 to 2021 and has an impact on the effect of urban heat islands through spatiotemporal analysis. The thermal load and dynamic potential layers are evaluated and integrated to generate a Climate Analysis Map to explore the hotspots of the study region. Based on the findings, the study concludes with plausible guidelines and strategies to minimize the impact UHI effect and to promote a sustainable built environment.
